On behalf of the Apache Hadoop Project Management Committee, I am pleased to announce the release of Apache Hadoop 3.3.5.
This is a release of Apache Hadoop 3.3 line. Key changes include * A big update of dependencies to try and keep those reports of transitive CVEs under control -both genuine and false positives. * Critical fix to ABFS input stream prefetching for correct reading. * Vectored IO API for all FSDataInputStream implementations, with high-performance versions for file:// and s3a:// filesystems. file:// through java native IO s3a:// parallel GET requests. * Arm64 binaries. Note, because the arm64 release was on a different platform, the jar files may not match those of the x86 release -and therefore the maven artifacts. * Security fixes in Hadoop's own code. Users of Apache Hadoop 3.3.4 and earlier should upgrade to this release. All users are encouraged to read the [overview of major changes][1] since release 3.3.4. For details of bug fixes, improvements, and other enhancements since the previous 3.3.4 release, please check [release notes][2] and [changelog][3]. *Azure ABFS: Critical Stream Prefetch Fix* The ABFS connector has a critical bug fix https://issues.apache.org/jira/browse/HADOOP-18546: *ABFS. Disable purging list of in-progress reads in abfs stream close().* All users of the abfs connector in hadoop releases 3.3.2+ MUST either upgrade to this release or disable prefetching by setting `fs.azure.readaheadqueue.depth` to `0`.
